OPTICAL SIGNAL SWITCH USING THE KERR EFFECT Russian patent published in 2020 - IPC G02F1/03 

FIELD: optical communication technique.

SUBSTANCE: invention relates to optical communication and can be used in designing equipment for high-speed soliton transmission systems. Switch of optical signals using Kerr effect includes polarization filter, after passing through which optical beam acquires vertical polarization and is exposed to electric field in electrooptical anisotropic substance with double refraction to change wave polarization. Further, the optical beam is transmitted simultaneously to two polarization filters, wherein in one filter, the polarization vector is deflected relative to the vertical axis by +45 degrees, and in another filter, the polarization vector is deviated from the vertical axis by -45 degrees.

EFFECT: technical result is reliable switching with high speed of light flux from one channel to another due to change of polarization plane under action of Kerr effect.
